最近,日本研究人员推出了一款带有发光二极管的放大镜,可在黑夜中有效地看清楚想看的东西。对于士兵、刑警和间谍来说,他们常常要执行比较特殊的任务,有时需要在黑暗的环境下继续工作,带发光二极管的放大镜对他们来说就非常有用。举个例子来说,某个间谍在夜晚潜入敌方的秘密机构,随身携带了一张缩微的地形图,在需要查看的时候,如果打开灯查看则会暴露目标。这时,间谍拿出一个带发光二极管的夜视放大镜,悄悄地放在缩微地形图上,就可清清楚楚地查到所需查找的信息。 Recently, Japanese researchers introduced a magnifying glass with a light-emitting diode to effectively see what they want to see during the night. For soldiers, cops and spies, they often have to perform more specific tasks, and sometimes need to work in a dark environment. A magnifying glass with LEDs is very useful for them. For example, a spy sneak into an enemy’s secret agency at night, carrying a tiny topographical map with you, revealing the target if you turn on the lights when you need to see it. At this time, the spy came up with a night-vision magnifier with LED, quietly placed on the miniature topographic map, you can clearly find the information you need to find.
